Page file size on a Windows 7 64 bit installation?

    Question

  • I would like to know how large the page file can get on a Windows 7 64bit installation?  Particularly under heavy usage, such as with 12 to 20 apps open?  Thanks for reading!

  • Let Windows manage the size!. It does it with the following schema:

    System Memory Size

    Minimum Page File Size

    Maximum Page File Size

    < 1 GB

    1.5 * RAM Size

    3 * RAM Size

    >= 1 GB

    1 * RAM Size

    3 * RAM Size

    The answer depends on how much RAM you have and on how much memory
    those 12 to 15 apps take (apps are of different sizes, and the files
    that you open with them also affect the amount of memory they use).

    But why do you want to know? If you are planning on creating a
    separate partition for the page file and want to know how big to make
    it, such a partition is not a good idea.

  • This depends on the amount of RAM you have in your Windows. Let Windows manage the size and you're fine in all situation.

  • It's true that the recommended amount to start with is 1.5 times the amount of RAM you have, but I think I've seen Windows grow a page file beyond that when needed.  I wouldn't put the page file on a separate partition from my OS installation, I'd actually put it on a separate drive apart from programs and the OS so that it could have its own drive usage and not contend with the programs and OS's drive requests.  Depending on how concerned I was with drive wear.

  • Thank you all for the input, it was all good.  JS2010, your blog reference was VERY good.  That was some nice insight into the paging process.
